This driving method realizes an AC-driving mode,removes the threshold voltage variation of the driving TFT due to the process variation or long-term operation,which can bring about brightness non-uniformity, and eliminates high peak pulse currents at the beginning and end of recovery time. Simulation is done with AIM-SPICE,and simulation results demonstrate that the OLED is in the reverse-biased state during recovery time.展开更多
